The diaphragm valve is specially used for controlling non corrosive or general corrosive medium, the inner surface of the valve body is not lined or covered with various rubber and non liner diaphragm valves which are suitable for different working temperature and liquid pipelines.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact. Body: cast iron, nodular cast iron, carbon steel, stainless steel
Valve cover: cast iron, nodular cast iron, carbon steel, stainless steel
Lining: no lining, rubber
Diaphragm: Rubber
Valve: Cast Iron
Stem: carbon steel, stainless steel
Hａnd wheel: Cast Iron Diaphragm valve is a special form of cut-off valve: 1, elastic seal open and close parts, to ensure no leakage;
2, streamlined runner, making the pressure loss small;
3, no stuffing, so no leakage;
4, the valve body and the cover is separated by the middle diaphragm, so that the diaphragm above the valve cover, stem and other parts from medium erosion;
5, diaphragm can be replaced, low maintenance costs;
6, lining material diversity, can be applied to various media, and has high strength, good corrosion resistance characteristics.
